# We are using a recursive build, so we need to do a little thinking # to get the ordering right. # # Most importantly: sub-Makefiles should only ever modify files in # their own directory. If in some directory we have a dependency on # a file in another dir (which doesn't happen often, but it's often # unavoidable when linking the built-in.o targets which finally # turn into vmlinux), we will call a sub make in that other dir, and # after that we are sure that everything which is in that other dir # is now up to date. # # The only cases where we need to modify files which have global # effects are thus separated out and done before the recursive # descending is started. They are now explicitly listed as the # prepare rule. |
